I'm using Ubuntu 16.04 on my laptop and I can't connect specifically to public Wifi. The hardware and driver work fine because I can connect to my personal pocket wifi. But when I try to switch to public wifi, for example the wifi in macdonald free wifi or the wifi in the hotel, I can't not connect to those public wifi. Those public wifi also set up fine because I can connect them with my ipad. When I try to connect to public wifi, it shows "Active connection removed before it was initialized" and just back to the status of no wifi connection.
Any hint about what may be happening?
